Adding 2.5 inch ssd to ZBook Studio G5 Mobile Workstation where there was none before?

[mwx]

The parts I think I need besides the ssd are 

L28674-001 (Bracket Kit)
L33681-001 (Hard Drive Hardware Kit)
L28668-001 SPS-CABLE KIT

which are all backordered at HP Parts.

The L28674-001 message is "This part is used in more than 200 products, we can not show the details" so II don't know what specific parts to look for elsewhere. I can see that the L28674-001 is missing from a photo I have. The L33681-001 lists other products which use it , so maybe I can find. It also needs  L28668-001 SPS-CABLE KIT because  no 2.5 disk was ever installed.

Are these what I need to add 2.5 ssd besides the ssd?
